Master Paint System MPS Disposable Paint Spray Gun Cup Liners and Lid System, 50 Pack Mini Size 6 Ounce (180ml) Kit - 50 Cup Liners, 50 Lids with Strainer, 1 Hard Cup with Retainer Ring and 20 Plugs

These things are guaranteed to make a mess of your gun, and shop floor. My window for returning them is closed, or I would send this garbage back. Save your money, and buy 3M...

I have used 3M PPS liners for years figured I’d give this a shot, they work just as good as the 3M brand ! Will continue to buy

I love these cups! Some reviews mention leaks, I have had none but probably because I am very careful assembling the cups. The liners are cool, they drop into the hard cup. Pour the paint in, then put on the top(with the feed hole and integrated filter). This is tricky, it has a number of clicks as it settles into the liner. It has to be settled all the way in, kind of subtle, I suspect if this is not done then leaks will be had. Next is to screw on the black retaining ring. This too is fiddly, very easy to cross thread. I sight from the side and watch it go on. Also when screwing it on it can be screwed on too tight and skip threads, it needs to be just tight enough. There are no directions and very few if any online tutorials so I will continue. Once filled and capped keep the cup with the orifice pointing up and push the gun onto the cup. This has a few hitches/bumps as it goes on. Once it is completely seated twist one notch for complete seal. Then attach the gun to air and pull trigger with the gun upside down and all the air will be sucked out of the cup, leaving only paint in the now collapsed liner. Very cool! This is what lets you paint upside down without sputtering, paint keeps flowing. I tried to refill a cup and it didnt go well. If I need more paint I use a new cup. If I have lots left over I put the cup on top of my paint can and let the un-used paint dribble back into the can. Overall way better than the stock metal reuse-able paint cup, I will never go back!

Great packaging! Easy self explanatory operation. Great product for clean environments.

Worked fine

save money on thinners and time cleaning the gun

Incomplete did not even get the right amount of lid vs cups. Missing plastic hard cup and black retaining lid. Did not get the plugs. Very disappointed. I would not recommend due to poor packaging, damaged replaceable cups and missing items. Not worth it. I should have trusted the rest of the reviews.

With these, it only takes a few minutes to clean your gun (the worst part of painting), and as a bonus you can spray upside down. A little tricky to get the cap on, but not bad enough to be a problem. They also eliminate the need for extra filters.

work good fast shipping
